The output shaft of the waterproof motor will drive the rotating shaft to rotate synchronously, and then drive the cutting knife to cut and crush the algae. The crushed algae will be drawn into the interior of the harvesting net frame. At the same time, because the water pump is working, the water pump will pump water near the rotating shaft into the interior of the harvesting net frame, and the algae debris floating near the rotating shaft can be sucked into the interior of the harvesting net frame, preventing the broken algae debris from scattering in the water, thereby increasing the algae cleaning effect.

The staff will first rotate the threaded rod and use the threaded connection between the threaded rod and the threaded hole to increase the distance between the connecting plate and the harvesting net frame, so that the depth of the harvesting net frame in the water can be adjusted, increasing the applicability of harvesting algae;
[0015] 3. After the harvesting net frame is lifted out of the water, the staff will flip open the flip plate and clean the algae debris in the harvesting net frame through the cleaning port. Before opening the flip plate, the staff will first rotate the blocking plate on the top of the positioning column to prevent the blocking plate from being blocked on the top surface of the flip plate, which increases the convenience of the staff in cleaning the algae debris inside the harvesting net frame.

[0023] During use, when the harvesting net frame 1 sinks into the water to harvest the algae in the water, the waterproof motor 3 is in working condition, and the rotating output shaft of the waterproof motor 3 will drive the rotating shaft 5 to rotate synchronously, and then drive the cutting knife 6 to cut and crush the algae. The crushed algae will be drawn into the interior of the harvesting net frame 1. At the same time, since the water pump 8 is working, the water pump 8 will pump the water near the rotating shaft 5 into the interior of the harvesting net frame 1, and the algae debris floating near the rotating shaft 5 can be sucked into the interior of the harvesting net frame 1, thereby preventing the broken algae debris from scattering in the water, thereby increasing the cleaning effect of the algae.
